Check the latest revision, theWhether or not you're new to FPV quads, you've probably heard of the. While it's a great starter rig it has some shortcomings. This guide provides instructions on how to build a higher quality, comparable quad at nearly the same price.
Scanning all available deals for Eachine Wizard X220 shows that the average price across all deals is $61.61. The lowest price is $4.99 from ebay while the highest price is $310.95 from ebay. New products prices vary between $4.99 and $310.95.
Some improvements include:. F4 flight controller for faster loop times. Dshot compatible 4-in-1 ESC. CCD camera for a wider dynamic range. OSD for real time voltage readings. Blackbox for tuning.
A more solid frame and better quality motorsThis is a fairly easy starter build as it doesn't require quite as many solder joints as a typical build. The 4-in-1 ESC saves about 16 joints. Also, this is a very roomy frame, so you've got lots of space for your RX as well as an HD camera. So let's get started!Frame AssemblyI had a few liberties with the kit, so I'll do my best to explain the build process. Most folks will screw the the frame together from the top. Instead, I excluded the red PDB and inserted the screws through the bottom.
This offers a much more flush bottom face. To mount the stack I inserted the same screws through the bottom and screwed the standoffs into them as pictured:Wiring the Motors and ESCsAfter securing all of the screws I mounted the motors and fitted the 4-in-1.
This particular ESC requires a little finesse around one of the standoffs. If the standoff isn't at the proper orientation it'll bump part of the circuitry under the board.
Just be sure it sits flush on top of all of the standoffs. You might want to consider some blue loctite to mount the motors as there's a small chance the motor screws can wiggle free over time. This is debatable, so it's really a suggestion rather than a requirement. Note: The bottom plate is backwards in the next couple pictures, so make sure the ESC FC plug is facing the front of the quad.The first thing you want to do is replace the power leads. The wires they used were far too thin for a quad of this size.
I used 16AWG which isn't ideal for a 4S build (14AWG would be better), but the pads were super tiny. It should be fine. Another problem is the motor wires are too short, so you need to join them to the pre-installed 4-in-1 wires. Ideally the motor wires should solder directly to the 4-in1 to reduce any potential point of failures.Soo, I decided to get a little fancy with the wires. The paracord is entirely optional, but I've always wanted to give it a try. At the very least you need a little shrink tubing to cover the joints. I cut 3 pieces of paracord to 2.6 inches each and slid them over the wires.
Then I cut a couple larger pieces of shrink tube to go over the paracord and 3 tiny pieces to go over each joint. You should tin the wires before adding any of the tubing to avoid melting it pre-maturely.At this point you can solder the wires, but be careful not to melt the shrink tube before you sleeve the joints. Get in quick and get out quick. Once it's soldered up you can sleeve the joints and melt the tubing. Before you melt the larger tubing over the paracord it's a good idea to take a lighter to the ends to reduce the fraying.I used a little double-sided tape to keep the wires down and here's how it turned out:Wiring the Flight ControllerNow for the fun part!

Wiring the FC and FPV gear can go really quick if you know where all the wires go. The first thing you need to do is send power to the board.
These go to the vbat and ground pads.Now that your board has power you can work on your FPV/OSD. This flight controller has 5v out but I found that it isn't enough amperage to power either the VTX or the camera, so you'll have to use the 5V BEC listed in the part list. To prepare the BEC remove the shrink wrap and de-wire it. Make sure you've got some shrink tube wide enough to cover it up afterward, or you can just use some electrical tape. I passed the vbat straight from the flight control board to the BEC and then connected both the camera and VTX power leads to the BEC output. It has terminals for two sets of wire on the output end. While this BEC isn't as small as a pololu, it'll get the job done.
Make be sure you buy the 5v BEC because 12v is too much for this little VTX.Finally, solder the camera video to the FC OSD in and the VTX video to the FC OSD out. That's it for the FPV wiring.Receiver and ESCsNow for the finishing touches! Depending on what TX/RX you're using the RX wiring will vary. Since I use a DSMX radio, I used a LemonRX diversity satellite. A nice trick to protect your antennas is to wrap zip-ties around the front arms pointed back toward the motors. Then you can use some shrink tube to affix them to the zip-ties where they'll never be affected by prop strikes or upside down 'landings'.
Finally, don't forget to connect your ESC board to the FC. Just use the short cable included in the package. ConfigurationNow you're ready to configure! As always, make sure your motors are in the proper positions and that they're spinning the proper directions. The first thing you need to do is flash to the latest stable release of BetaFlight. Keep in mind that this board uses the Omnibus F4 distribution. If you use the same components listed below you can re-arrange the motors with these CLI commands: resource MOTOR 1 A03resource MOTOR 2 A02resource MOTOR 3 B01resource MOTOR 4 B00saveAfter that you'll want to reverse the motor direction through BLHeli Configurator.
In my case I needed to reverse motors 2 and 3. This ESC supports DSHOT300, so be sure to toggle that. And since this is an F4 board you can run both your PID loop and Gyro at 8khz.
Now the rest is up to you! You'll want to bind and map your receiver, set your modes (ARM, AIR MODE, HORIZON, etc.), and configure your OSD. One nice thing about dshot is you won't need to calibrate your ESCs. Camera SettingsOne important step that I usually take care of last is adjust the camera settings. You'll need to hook it up to an analog screen using the included wire harness. The power lead is perfect for a Fatshark battery, but if you don't have one you can just use a laptop power supply. Just make sure the voltage and polarity are correct.
If you set your camera according to that document you'll be all set!Final weight with Mobius Mini: 356gPhotos. Hey!Beautiful, super clean build. I absolutely love the paracord idea and refuse to use anything else now.;)I'm currently planning a Martian II build myself as a first racer (a first build as well, figured I'd be better off putting something together myself).What I'm planning on using is a BG's F3 controller, Matek PDB and 30A BLHeli ESC (I'd like to use 4S in the future as well as 5045 props. Gotta practice that soldering!).As for the camera I'd use a Runcam Swift 2 with the same VTX. As far as I know I wouldn't need a separate BEC for this config, right?I also can't figure out how to wire the VTX and camera as I've seen many people do it in different ways.Should I wire it through the PDB or wire the camera through the VTX?
Does it change the amount of possible noise? What do you think?I'd love your input as I can see you sure know how to put these together.;)Cheers! It really depends on your target price.
This is still about as cheap as you can go without using junk parts, but if you don't mind spending a bit more you might want to consider 30A ESCs. The Racerstar StarF3S board will do the trick for nearly the same price as the two boards and the regulator board listed here, but you may have issues binding the Turnigy, so I'd look into that. Other than that you can consider a different frame like the Frog Lite 218mm which is pretty nice, but it's a tighter fit.
The Runcam Swift is a nice choice if you want to do HD recording, but it's not quite available yet. @whiffles I'm just getting into the hobby and I decided that this would be my first build. I was looking hard at the Eachine Wizard to start, but I wanted a bit more of a challenge than a pre-packaged kit. I'm proud to say I built this drone and it is just awesome! Thank you so much for the detailed pictures and descriptions.

You've made so that even an absolute beginner can replicate the build easily.Here's a photo, if you look closely you'll notice that my soldering and wiring skills are absolutely terrible. But, I think this is a great starter build if you're patient and careful! I used 16AWG for the main battery leads because the pads are too small for 14AWG. Now the wires going to the motors are much smaller.
If you get a 4-in-1 without wires pre-soldered then you'll need to come up with about 2cm of additional wire per motor and that's more like 22AWG or 24AWG, I'm not sure. If you have no particular reason to get the V2 BB2 4-in-1 then you might as well get the one I used. It works just fine, you'll save a few dollars and you won't need to worry about coming up with additional wire.
Greetings,recently I bought an Eachine Wizard X200S from Banggood.After I opened it, I had to replace the reciever cable to connect the drone with my Flysky i6, but it wasn't a problem. I paired the drone with the controller successfully and then I did some settings in CleanFlight.Because I'm relatively new in this hobby, I used this video as inspiration: (22nd minute).Everything seemed to work properly, but then I finally tried to fly. And here is the problem.I just can't start the motors. According to the settings I did, motors should get armed with one of the switches on controller, but it doesn't work. I tried the original arming (with right joystick position) too, but without any result.The I connected the drone with PC again, and found out that even CleanFlight isn't recieving any informations from controller. I'm pretty sure that I did the pairing right, because in the controller screen I can see informations about the drone.Does anybody here know where is the problem?
I think it's just the arming, but it can be anything.Thanks in advanceMichael P.
